Duster/Demon seat belt anchor

Thanks guys. The ones I need are for the outboard seatbelt. They are a male stud so the seatbelt attaches with a nut for the outboard seatbelt on the 72 demons and dusters anyway. I don't see these being reproduced anywhere. My car does have those brackets with nuts for the inboard seatbelts like the pictures 67 posted...thanks for the help everyone
